Operation Platinum...Needs some work

  (Edited: )

Hey guys,
Now that Summer break is here I've been debating something for a while, I really want to get "Good" at SC2 (Plat+ hopefully).
I am currently a Silver league Protoss player (Demoted from Gold as I switched from Zerg) and have no real limit on time I can play per day, and I have about 6 weeks to do it in.

First question: Is it feasible?
Second Question: If so, how would I go about starting it? (As in, would I need a strategy for each match up per map...Should I practise them before hand or just jump into ladder etc...)

Cheers guys!
